Ho does it suggest that the sample mean and median will compare? The display is reasonably symmetric, so the mean and median wilt be close The display is negatively skewed, so the mean will be greater than the median The display is positively skewed, so the median will be greater than the mean, The display is negatively skewed, so the median will be greater than the mean. The display is positively skewed, so the mean will be greater than the median. (b) Calculate the values of the sample mean and median . (Hint: 1x, = 9628.) (Round your answers to two decimal placer.) 1. By how much could the largest time, currently 422, be increased without affecting the value of the sample median) Enter co it there is no limit to the mount) By how much could this value be decreased without affecting the value of the sample median interop if there is no limit to the amount (d) What are the value of and when the observations are expressed in minutes?
